Answer:
2.94 joules.
Step-by-step explanation:
Definition of terms
GPE is the Gravitational potential Energy. Potential Energy is actually energy possess by an object due to its position.
mass is the quantity of matter in a body, measured in kilogram, gram, pounds etc
gravity is the earth's magnetic pull on an object to its center
GPE=mass x gravity x height
mass=0.3kg
gravity=9.8m/s^2
height=1m
mass x g x height = 0.3 x 9.8 x 1 = 2.94 joules.
